Ruri is a very popular idol (many characters have reportedly confessed to be her fans, among them Shinra, Togusa, and several Awakusu-kai members), one of her selling points being her fragile good looks. She's originally a makeup artist and is in charge of Kasuka's vampire makeup in Kasuka's first TV show.
